相关申请的交叉引用
本申请要求在2022年06月02日提交中国国家知识产权局、申请号为202210625704.2、申请名称为“一种通信方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
随着物联网的发展，在数据与智能化越来越多地参与未来产业定义时，精准的位置服务在物联网发展中发挥了不可替代的作用，业界对高精度定位的需求也越来越高。如工业级精密行业、自动导引车(automated guided vehicle，AGV)导航、自动驾驶等场景均存在高精度定位需求。因此，如何实现高精度定位是现阶段需要解决的一个重要问题。
定位精度很大程度上依赖定位信号的带宽，带宽越大，定位精度越高。然而，大多数运营商频谱呈现“离散化”或者“碎片化”的现象，很难获得一段大带宽频谱。目前，可以采用载波聚合(carrier aggregation，CA)技术，在聚合的多个载波上发送或接收信号。对于接收端来说，可基于这多个载波上的信号进行相应的测量，获得更优的定位性能。
然而，不同载波上发送的信号之间可能存在相位不连续的问题，由此可能给测量结果造成较大的误差，进而影响定位性能。
发明内容
本申请实施例提供一种通信方法及装置，用于减小由于信号之间相位不连续而带来的误差。
第一方面，提供第一种通信方法，该方法可由第一设备执行，或由包括第一设备功能的其他设备执行，或由芯片系统或其他功能模块执行，该芯片系统或功能模块能够实现第一设备的功能，该芯片系统或功能模块例如设置在第一设备中。该方法包括：接收第一信息，所述第一信息包括第二设备在M个资源上的信息，所述M个资源为频率资源，M为正整数；在所述M个资源中的一个或多个资源上接收来自所述第二设备的第一信号；获得测量信息，所述测量信息是基于所述第一信号和所述第一信息确定的。
在一种可选的实施方式中，所述第二设备在所述M个资源上的信息，包括所述第二设备在所述M个资源上的相位信息，和/或，所述第二设备在所述M个资源上的能力信息。
本申请实施例中，第一设备在M个资源中的一个或多个资源上接收信号后，可以根据第一信息确定所接收的信号之间的相位信息，从而在获得测量信息时可以考虑所接收的信号之间的相位信息，降低不同信号之间相位差带来测量误差，提高所获得的测量信息的准确性。
由于第一信息可以包括第二设备在M个资源上的相位信息，和/或，包括第二设备在 M个资源上的能力信息，因此下面分为两部分来介绍。
1、第一信息包括第二设备在M个资源上的相位信息。
在一种可选的实施方式中，所述M个资源中的第一资源属于第一资源组合，所述第一信息包括所述第二设备在所述第一资源组合中的所述第一资源上的相位信息。
在一种可选的实施方式中，所述第二设备在所述第一资源组合中的所述第一资源上的相位信息，包括如下一项或多项：所述第二设备在所述第一资源组合中的所述第一资源上的相位；所述第二设备在所述第一资源组合中的所述第一资源上的相位个数；所述第二设备在所述第一资源组合中的所述第一资源上的相位取值集合；所述第二设备在所述第一资源组合中的所述第一资源上的相位取值范围；所述第二设备在所述第一资源组合中的所述第一资源上的相位误差信息；所述第二设备在第二资源上与所述第二设备在所述第一资源组合中的所述第一资源上的相位差，所述第二资源是所述M个第一资源中除所述第一资源外的任一个资源；或，所述第二设备在所述第一资源组合中的所述第一资源上的相位与参考相位的差值。
在一种可选的实施方式中，所述第二设备在所述第二资源上与在所述第二设备在所述第一资源组合中的所述第一资源上的相位差不为0。该方式下，第一设备接收的第一信息可以包括不为0的相位差，或者说，第一信息中的相位信息，为与第一资源存在相位差的资源的相位信息。对于第一设备来说，如果发现第一信息并未包括某些资源之间的相位差，则可以确定这些资源之间的相位差为0。这样既能够使得第一设备获得资源之间的相位差，也能减少第一信息的容量，从而减小信令开销。
在一种可选的实施方式中，所述第二资源属于第二资源组合，所述第二资源组合与所述第一资源组合为同一个资源组合，或者，所述第二资源组合与所述第一资源组合为不同的资源组合。
在一种可选的实施方式中，所述第一资源组合为一个或多个频带组合。

在一种可选的实施方式中，M个资源中的第一资源为一个资源集合，M个资源为M个资源集合。
该方式下，第一信息就可以包括第二设备在M个资源集合中的至少一个资源集合上的相位信息，通过资源集合的粒度就可以上报第二设备所对应的相位信息。既能够上报较为完善的内容，也有助于减小信令开销。
在一种可选的实施方式中，所述资源集合为载波集合，M个资源集合为M个载波集合，第一资源集合为第一载波集合。
在一种可选的实施方式中，所述第一资源为频带组合，M个资源为M个频带组合；或者，第一资源为频带，M个资源为M个频带；或者，第一资源为载波，M个资源为M个载波。基于上述方式，在一些场景下，第二设备在一个频带组合上会使用同一个通道，或者无论一个频带属于哪个频带组合，第二设备在该频带上都使用同一个通道，或者无论一个载波属于哪个频带组合，第二设备在该载波上都使用同一个通道，那么第一信息可以考虑采用这种实现方式。这种实现方式较为简单，能够节省第一信息所带来的传输开销。

在一种可选的实施方式中，所述第一信息承载于能力信息中。例如，第一信息承载在第二设备的能力信息消息中。

在一种可选的实施方式中，第一资源组合中的第一资源的频率范围，包括第二设备在第一资源组合中的第一资源上发送信号时使用的各个通道的频率范围。该方式下，第一设备根据该频率范围，能够确定第二设备在第一资源组合中的第一资源上所发送的信号之间的相位差。
在一种可选的实施方式中，第二设备在第一资源组合中的第一资源对应的分频系数，包括第二设备在第一资源组合中的第一资源上发送信号时使用的各个通道的分频系数。改方式下，第一设备如果获知了一个通道的分频系数，就能确定第二设备在该通道上发送的信号的相位取值集合或相位取值范围或相位，从而能够确定第二设备在该通道上发送的信号的相位。
在一种可选的实施方式中，所述第一资源为一个或多个频带，或为一个或多个载波。
在一种可选的实施方式中，所述第一资源组合为一个或多个频带组合。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，对本申请实施例中的部分用语或概念进行解释说明，以便于本领域技术人员理解。
(1)载波聚合。
载波聚合技术通过把可用频段的分量载波(component carrier，CC)组合起来，以达到提高频谱利用效率、提高数据速率、改善网络性能的效果。以两个分量载波参与聚合为例，载波聚合可包括几种类型，下面举例介绍。
如果这两个CC所属的频段(“频段”也可称为“频带”)相同，并且在频域上连续。则这两个分量载波的聚合称为频带内连续的载波聚合(intra-band contiguous CA)。例如图1中频带A上的CC1和CC2的聚合。需要说明的是，一些场景下，若两个CC所属的频段相同，且两个CC之间存在保护带宽，由于保护带宽占用的频谱较小，此时也可以认为这两个CC是连续的。
如果这两个分量载波所属的频带相同，但在频域上不连续，则这两个分量载波的聚合称为频带内非连续的载波聚合(intra-band non-contiguous CA)。例如图1中频带B上的CC3和CC4的聚合。
如果这两个分量载波所属的频带不同，则这两个分量载波的聚合称为跨频带的载波聚合或频带间载波聚合(intra-band CA)。例如图1中频带A上的CC1和频带B上的CC3的聚合。
(2)频段组合(band combination，BC)。
一个BC可以包括一个或多个频带，由于一个频带可以包括一个或多个载波，因此也可理解为，一个BC可包括一个或多个载波。
每个BC对应一个特性集组合(FeatureSetsCombination，FSC)，一个频段组合中的每个频段(band)对应一个该频段的特性集(FeatureSetperBand)。例如，频段特性集包括上行特性集(FeatureSetUplink)和下行特性集(FeatureSetDownlink)；每个载波对应一个载波特性集(FeatureSetPerCC)，例如载波特性集包括上行载波特性集(FeatureSetDownlinkPerCC)和下行载波特性集(FeatureSetDownlinkPerCC)。UE可通过特性集来上报该UE的能力，例如上报频段组合的能力、频段组合中每个频段的能力、或频段组合中每个载波的能力中的一项或多项。可选的，每个特性集可以通过一个标识(identifier，ID)来体现。
可参考图2，为一种FSC的示例。该FSC ID为1，该FSC例如对应BC1和BC2。其中，BC1为频带n41、频带n78和频带n88的组合，其中频带n41中参与BC1组合的载波数为8、频带n78中参与BC1组合的载波数为4、频带n88中参与BC1组合的载波数为2。BC2为频带n41和频带n78的组合，其中频带n41中参与BC2组合的载波数为4、频带n78中参与BC2组合的载波数为4。该FSC可包括频带n41、频带n78和频带n88的特征集，以频带n41的特征集为例，该特征集又包括频带n41对应于BC1的特征集1和对应于BC2的特征集2。例如频带n41对应于BC1的特征集1包括特征集下行ID1(FeatureSetDownlink ID1)和特征集上行ID1(FeatureSetUplink ID1)，分别表示频带n41在BC1中的下行能力和上行能力。例如在频带n41对应的特征集1的特征集下行ID1中又包括频带n41中参与BC1组合的8个载波的ID，例如分别为特征集1中的分量载波ID(FeatureSetPerCC ID) 1～8。又例如，频带n41对应于BC2的特征集2包括特征集下行ID1(FeatureSetDownlink ID1)和特征集上行ID2(FeatureSetUplink ID2)，分别表示频带n41在BC2中的下行能力和上行能力。在频带n41对应的特征集2的特征集下行ID1中又包括频带n41中参与BC2组合的4个载波的ID，例如分别为特征集2中的分量载波ID(FeatureSetPerCC ID)1～4。对于该FSC包括的其他内容也是类似的，不多赘述。
(3)用户网络接口通用(user to network interface universal，Uu)定位Uu定位，定位参考信号、定位辅助数据、定位测量结果等信息的传输均通过Uu口进行。其中，Uu中的“U”表示用户网络接口(user to network interface)，Uu中的“u”表示通用(universal)。Uu接口为蜂窝通信接口，需要接入网设备参与。
(4)侧行(sidelink，SL)定位SL定位，是一种利用SL发送侧行定位参考信号(sidelink positioning reference signal，S-PRS)并进行定位测量的技术。其中，UE之间可通过PC5(proximity based services communication 5，近距离服务通信5)接口传输定位参考信号，但定位辅助数据、定位测量结果等信息可以通过PC5接口或者Uu接口进行传输。
(5)定位参考信号。
定位参考信号可以理解为能够用于定位或者为定位提供参考的信号。本申请各个实施例中，定位参考信号可包括下行定位参考信号(downlink positioning reference signal，DL-PRS)、上行探测参考信号(uplink sounding reference signal，UL-SRS)、定位参考信号(positioning reference signal，PRS)、或S-PRS中的一种或多种。另外，其余参考信号如信道状态信息参考信号(channel state information reference signal，CSI-RS)、同步信号和物理广播信道(physical broadcast channel，PBCH)块(synchronization signal and PBCH block，SSB)、时频跟踪参考信号(Tracking Reference Signal，TRS)中的一种或多种也可用于定位，本申请中的定位参考信号为能够用于定位信息的参考信号，本申请实施例对定位参考信号的具体形式不作限定。
DL-PRS，用于下行定位方法和上下行联合定位方法。
UL-SRS，从广义的角度来说，SRS可包括用于多输入多输出(multiple input multiple output，MIMO)的上行参考信号(即MIMO-SRS)，以及专用于定位的上行定位参考信号(即定位探测参考信号(positioning–SRS，pos-SRS))。其中，MIMO-SRS和pos-SRS都可以用于上行定位方法和上下行联合定位方法。另外，在用于定位时，UL-SRS也可称为上行定位参考信号。
PRS，可包括DL-PRS和/或UL-SRS。
S-PRS，在SL上传输并专用于SL场景下的定位的参考信号。

(9)通道。
通信为通信设备发送和/或接收信号时的路径。其中，如果一个设备通过同一个通道发送多个信号，则这些信号之间的相位连续；而如果一个设备通过不同的通道发送信号，则这些信号之间的相位可能是连续的，也可能是不连续的，取决于每个通道上的随机相位。
(10)资源上的相位信息。
一个通信设备在一个资源上的相位信息，可以理解为该通信设备在该资源上发送信号时的相位信息或者随机相位信息，或者理解为该通信设备该资源对应的通道(例如射频通道)上发送信号时的随机相位信息。
由于硬件电路实现的原因，针对在一个通道上发送的信号来说，该信号从发送端的基带电路到射频电路的过程中会发生相位跳变，跳变后的相位为随机相位。例如，以第二设备为例，第二设备的基带电路生成的信号1的相位为A，而信号1从第二设备的基带电路到达第二设备的射频电路后，相位变成了B，若B与A不同，则信号产生了相位跳变，其中跳变后的相位B，即随机相位。其中，信号的随机相位可满足如下关系：
公式1中，表示随机相位。示例性地，公式1中的为相对稳定的数值，例如可建模 成高斯分布，其均值相对稳定，与设备的芯片内部设计相关，另外，可在一定范围内抖动，即存在方差。公式1中的为随机值部分，与该通道的分频系数有关，N表示该通道的分频系数。例如，当N＝4时，表示设备在该通道上能够实现四分频，可以为{0°,90°,180°,270°}四个值中的任意一个。在实际发送过程中，可能是{0°,90°,180°,270°}中的一个值，即，当N＝4时，{0°,90°,180°,270°}可以理解为是随机值的取值范围或取值集合。
又例如，当N＝8时，表示设备在该通道上能够实现八分频，可以为{0°,45°,90°,135°,180°,225°,270°,315°}八个值中的任意一个。在实际发送过程中，可能是{0°,45°,90°,135°,180°,225°,270°,315°}中的一个值，即，当N＝8时，{0°,45°,90°,135°,180°,225°,270°,315°}可以理解为是随机值的取值范围或取值集合。
本申请的各个实施例所提到的“不同信号之间存在相位差”或“不同信号的相位不连续”，指的是这些信号不能拼接或合成一个等效的大带宽信号。示例性地，信号发送端发送了5个带宽为20MHz的参考信号，这5个带宽在频域上可以连续也可以不连续，在频域上也可存在间隔或重叠，信号接收端可以将该5个信号拼接后得到一个带宽接近100MHz的信号，该拼接得到的信号的特征与信号发送端直接发送一个带宽接近100MHz(在频域上连续)的信号的特征类似或相同。
(11)资源与通道的关系。本申请中，资源也可以理解为包括频域资源或频率资源，例如，第一资源可包括一个或多个(或，一份或多份)频率资源。“频率资源”是指在频域上连续的一段频谱资源，一个通道对应一个或者多个资源。由于资源的粒度可以有多种，一个资源是一个子载波、一个或者多个资源块(resource block，RB)、一个带宽部分(bandwidth part，BWP)、一个分量载波、一个频带(band)、一个频段、频率层(frequency layer)、频点(frequency point)、或频率范围(frequency range，FR)。
例如，以频带为例，不同的频带可以对应不同的通道。可参考图1，例如频带A和频带B对应的通道不同。又例如，同一个频带上的非连续的载波对应的通道不同。例如图1中，频带B上的CC3和CC4可以对应不同的通道。或者，在某些场景下，同一个频带上的非连续的载波也可能对应同一个通道，例如对于高频率的频带，则该频带上的非连续的载波可能对应同一个通道。又例如，同一个频带上的连续的载波可能对应同一个通道。例如图1中，频带A上的CC1和CC2可以对应同一个通道。或者，在某些场景下，同一个频带上的连续的载波也可能对应不同的通道。再例如，同一个载波可以对应同一个通道。例如图1中，CC1可对应一个通道，一个设备无论在CC1的哪个频率位置发送信号，都使用同一个通道。或者，在某些场景下，同一个载波也可能对应不同的通道，例如在不同的频带组合中，同一个载波可以对应不同的通道。
本申请实施例中，对于名词的数目，除非特别说明，表示“单数名词或复数名词”，即"一个或多个”。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。例如，A/B，表示：A或B。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，表示：a,b,c,a和b,a和c,b和c,或a和b和c，其中a,b,c可以是单个，也可以是多个。
本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的大小、内容、顺序、时序、优先级或者重要程度等。例如，第一信令和第二信令，可以是同一个信令，也可以是不同的信令，且，这种名称也并不是表示这两个信令的内容、信息量大小、发送顺序、发送端/接收端、优先级或者重要程度等的不同。另外，本申请所介绍的各个实施例中对于步骤的编号，只是为了区分不同的步骤，并不用于限定步骤之间的先后顺序。例如，S401可以发生在S402之前，或者可能发生在S402之后，或者也可能与S402同时发生。
下面介绍与本申请实施例相关的技术特征。
通过研究发现，定位精度在很大程度上依赖于定位信号带宽。一般来说，对于基于时延信息的定位方法来说，例如TDOA定位和无线传输技术(adio transmission technology，RTT)定位，定位信号的带宽越大，则定位精度越高。为了提高定位精度，对于待定位的UE来说，一种获得大带宽的方式为，采用载波聚合方式来获得大带宽。在这种方式下，可以在参与聚合的多个载波上发送定位信号，接收端可以将接收的多个定位信号“拼接”成一个大带宽的参考信号(其带宽接近发送端发送的信号占用的总带宽之和)，从而获得较高的定位精度。但由于各个载波上的信号之间存在相位差，导致定位精度有所降低。鉴于此，提供本申请实施例的技术方案。本申请实施例中，第一信息可包括第二设备在M个资源的相位信息。那么第一设备在M个资源中的一个或多个资源上接收信号后，可以根据第一信息确定来自不同资源上的不同信号的相位信息，从而根据相位信息避免可能存在的测量误差。例如该测量信息的一种应用场景为，该测量信息可用于定位测量。那么，通过本申请实施例的技术方案，第一设备通过获取一个或者多个资源上的相位信息，可以采用相应的方式减小或消除不同信号之间的相位差，以提高定位的精度。
本申请实施例提供的技术方案可以应用于各种通信系统，例如：全球移动通信(global system for mobile communications，GSM)系统，码分多址(code division multiple access，CDMA)系统，宽带码分多址(wideband code division multiple access，WCDMA)系统，通用分组无线业务(general packet radio service，GPRS)，长期演进(long term evolution，LTE)系统，LTE频分双工(frequency division duplex，FDD)系统，LTE时分双工(time division duplex，TDD)，通用移动通信系统(universal mobile telecommunication system，UMTS)，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，第五代(5th generation，5G)系统或新无线(new radio，NR)等，或者还可以应用于下一代移动通信系统或其他类似的通信系统，具体的不做限制。另外本申请实施例提供的技术方案可以应用于设备到设备(device-to-device，D2D)场景，例如NR-D2D场景等，或者可以应用于车到一切(vehicle to everything，V2X)场景，例如NR-V2X场景等。例如可应用于车联网，例如V2X、车与车(vehicle-to-vehicle，V2V)等，或可用于智能驾驶、辅助驾驶、或智能网联车等领域。如果应用于D2D场景，则通信双方可以均为UE；如果应用于非D2D场景，则通信的一方可以是UE，另一方是网络设备(例如接入网设备)，或者通信双方可能均为网络设备。在下文的介绍过程中，以通信双方分别是UE和接入网设备为例。
请参考图3，为本申请实施例的一种应用场景示意图。图3包括UE(也可称为目标UE)，接入网设备1和接入网设备2，AMF和LMF等核心网设备，以及包括校准设备。需注意的是，图3以两个接入网设备为例，实际通信系统包括的接入网设备还可以是三个 或三个以上。其中，接入网设备1例如为该目标UE的服务接入网设备。校准设备能够与目标UE和接入网设备通信，可选的，校准设备还能与LMF通信。该校准设备例如为接入网设备或UE。图3中，例如接入网设备1和接入网设备2属于下一代(next generation，NG)RAN，接入网设备之间通过Xn接口通信。NL1表示AMF与LMF之间的通信接口。
其中，LMF的控制面为增强服务移动位置中心(enhanced serving mobile location centre，E-SMLC)，LMF的用户面为安全用户面定位(secure user plane location，SUPL)定位平台(SUPL location platform，SLP)。LMF负责支持有关目标UE的不同类型的位置服务，包括对目标UE进行定位以及向目标UE传递辅助数据等。
AMF可以接收与目标UE相关的位置服务请求，该位置服务请求用于请求对目标UE进行定位。或者AMF也可以自行启动针对目标UE的位置服务，例如AMF可自行生成位置服务请求。AMF可将该位置服务请求发送给LMF，以启动对目标UE的定位过程。
如果是下行定位过程，则目标UE可以测量来自接入网设备或其他设备的定位参考信号，以对该目标UE进行定位。
接入网设备可以为目标UE提供相应的信息，例如为UE配置定位参考信号，还可能向UE发送定位参考信号等。接入网设备还可将用于配置定位参考信号的信息发送给LMF。
为了更好地介绍本申请实施例，下面结合附图介绍本申请实施例所提供的方法。在本申请的各个实施例对应的附图中，凡是可选的步骤均用虚线表示。本申请的各个实施例所提供的方法均可应用于图3所示的场景。例如，本申请的各个实施例所涉及的第一设备为图3中的UE、接入网设备1、接入网设备2或LMF。本申请的各个实施例所涉及的第二设备例如为图3中的接入网设备1、接入网设备2、或UE。本申请的各个实施例所涉及的第三设备例如为图3中的第二设备、校准设备或LMF。
本申请的各个实施例中，UE可以通过无线资源控制(radio resource control，RRC)信令向接入网设备发送信息；或者，UE可以将待发送的信息发送给LMF(例如UE通过LTE定位协议(LTE positioning protocol，LPP)消息将该信息发送给LMF)，LMF再将该信息中的部分或全部内容或将该信息进行调整/修改后的内容发送给接入网设备(例如LMF通过NR定位协议附属(NR positioning protocol annex，NRPPa)消息将该信息发送给接入网设备)。接入网设备可以通过广播消息或单播消息向UE发送信息，广播消息例如系统信息块(system information blocks，SIB)或定位系统信息块(positioning system information blocks，posSIB)，单播消息例如为RRC信令；或者，接入网设备可以将待发送的信息中的部分或全部内容或将待发送的信息进行调整/修改后的内容发送给LMF(例如接入网设备通过NRPPa消息将信息发送给LMF)，LMF再将该信息发送给UE(例如LMF通过LPP消息将该信息发送给UE)。校准设备可以是终端类型的设备，或者接入网设备类型的设备，或者其它类型的设备。校准设备和第一设备/第二设备之间的信息交互取决于校准设备的类型，可参考上述描述，本申请不做限定。校准设备可将待发送的信息发送给第一设备，或者通过其它设备(如第二设备、接入网设备、LMF等)发送给第一设备等等，后文的信息发送过程均可参考本段的描述，后文不再多赘述。
本申请实施例提供第一种通信方法，请参见图4，为该方法的流程图。
S401、第三设备发送第一信息。相应的，第一设备接收第一信息。
其中，如果将本申请实施例的技术方案应用于定位场景，则本申请实施例提供的定位过程可以是上行定位、下行定位、联合上下行定位、测距/测角/测相(不区分上下行)、感 知(Sensing)过程。下述以上行定位过程为例进行说明，例如第二设备为UE，第一设备为接入网设备；或者，本申请实施例提供的定位过程可以是下行定位过程，例如第二设备为接入网设备，第一设备为UE；或者，本申请实施例提供的定位过程也可以是上下行定位过程，例如在上下行定位过程中，可以执行两次本申请实施例的方法，在其中的一次执行过程中，第二设备为UE，第一设备为接入网设备，在其中的另一次执行过程中，第二设备为接入网设备，第一设备为UE。另外，参与定位的可能有多个接入网设备，本申请实施例是以描述了其中一个接入网设备的行为。可选的，该接入网设备例如为UE的服务接入网设备。在上述场景中，第三设备可以与第一设备或第二设备为同一设备，或者第三设备也可以是其它设备，例如，第三设备为LMF，或为除第一设备和第二设备之外的UE或接入网设备等。
第一信息可包括(或，指示)第二设备在M个资源的相位信息。可选的，第二设备在M个资源的相位信息，可以理解为第二资源在M个资源对应的相位信息。因此也可以理解为，第一信息可包括(或指示)第二设备在M个资源对应的相位信息。示例性的，M个资源为M个频率资源，例如M个资源为第二设备所支持的全部或部分频率资源，M为正整数。可选的，M个资源为第二设备所支持的频率资源中用于定位的频率资源，相当于只是将第二设备在用于定位的频率资源上的相位信息发送给第一设备，无需将第二设备在其他业务或功能的频率资源上的相位信息发送给第一设备，这样不会过多暴露第二设备的硬件实现，有利于保护第二设备的隐私与安全。
本申请实施例中，M个资源中的一个资源可对应一个或多个通道，例如，M个资源一一对应M个通道。又例如，M个资源中的一个资源对应多个通道。再如，M个资源中的多个资源对应一个通道。
可选的，如果不同的频带对应不同的通道，而一个频带上的所有载波对应同一个通道，则M个资源例如为M个频带；或者，如果不同的载波对应不同的通道，则M个资源例如为M个载波；或者，如果一个频带上连续的载波对应同一个通道，而一个频带上不连续的载波对应不同的通道，则M个资源中的一个资源例如为频带1上的连续的多个载波，而M个资源中的另一个资源例如为频带2上的载波1，载波1与频带2上的其他载波不连续，频带1与频带2为同一频带，或者为不同的频带。除此之外，M个资源还可能有其他实现方式，只要其中的一个资源对应一个通道即可。
值得注意的是，第一信息指示第二设备在M个资源上发送信号时的相位信息，但并不一定表示第二设备在所述过程中在M个资源中的所有资源上均发送了信号，也可以是在M个资源中的部分资源上发送信号。
第一信息可以有多种实现方式，下面举例介绍。
1、方式1。
M个资源可以属于一个或多个资源组合，第一信息可以包括第二设备在这一个或多个资源组合中的至少一个资源组合中的资源上的相位信息。以M个资源中的第一资源为例，第一资源可以为M个资源中的任一个资源，M个资源包括第一资源。第一资源属于第一资源组合。在这种实现方式下，第一信息可以包括第二设备在第一资源组合中的第一资源上的相位信息。
可选的，当资源组合为频带组合，此时，第一资源组合为第一频带组合。由于一个频带组合可以包括一个或者多个载波，或者包括一个或者多个频带，因此，第一资源可以是 一个载波或者一个频带。如果第一资源为一个频带，那么第一信息可包括第二设备在一个或多个频带组合中的至少一个频带组合中的部分或全部频带上的相位信息；或者，第一资源为一个载波，那么第一信息可包括第二设备在一个或多个频带组合中的至少一个频带组合中的部分或全部载波上的相位信息。
上述方式1中，第一资源可属于多个资源组合，或者说，M个资源所包括的多个资源组合中，有两个或者两个以上的资源组合均包括第一资源，此时，第一资源可以对应多个通道。
在前文介绍了，第一资源可以属于第一资源组合，在一种可选的方式中，如果第一资源对应多个通道，则第一资源属于多个资源组合。以第一资源属于第一资源组合和第二资源组合为例，此时，第一信息可以包括第二设备在第一资源组合中的第一资源上的相位信息，和第二设备在第二资源组合中的第一资源上的相位信息。
举例来说，M个资源为频带1～频带3，例如这3个频带可能组成4个频带组合，分别为频带组合1、频带组合2、频带组合3和频带组合4。其中频带组合1包括频带1和频带2，频带组合2包括频带1和频带3，频带组合3包括频带2和频带3，频带组合4包括频带1、频带2和频带3。例如第一资源为频带1，可见，频带1属于频带组合1，也属于频带组合2，还属于频带组合4。第一信息可指示第二设备在频带组合1中的频带1上的相位信息，以及指示第二设备在频带组合2中的频带1上的相位信息。
示例性地，第二设备如果在同一频带上的两个非连续的载波上发送信号，可以通过两个通道发送，不同的载波可对应不同的通道，即，非连续载波可能会使用不同的通道。例如，图1中的CC3和CC4是属于频带B的非连续载波，频带B属于两个频带组合，例如分别为频带组合1和频带组合2。则可能存在两种情况：
第一种情况，CC3和CC4属于不同的频带组合中的频带B，例如CC3属于频带组合1中的频带B，CC4属于频带组合2中的频带B。一种可能的实现方式，将CC3的相位信息与频带组合1中的频带B关联，CC4的相位信息与频带组合2中的频带B关联，即需要上报两个相位信息。
第二种情况，CC3和CC4属于相同的频带组合中的频带B，例如CC3和CC4均属于频带组合1中的频带B。一种可能的实现方式，将CC3和CC4的相位信息与频带组合1中的频带B关联，即只需要上报一个相位信息。
如果是第一种情况，第二设备在同一个频带所包括的非连续的载波上的相位信息可能是不同的。为了将第二设备在该频带上的相位信息均告知第一设备，可将该频带分别包括在不同的频带组合中，且该频带在不同的频带组合中包括的可以是不同的载波，这样就可将第二设备在非连续载波上的相位信息指示给第一设备。一种可能的实现方式，在频带组合1中频带B包括CC3，在频带组合2中频带B包括CC4。第一信息可指示第二设备在频带组合1包括的频带B上的相位信息，相当于指示第二设备在CC3上的相位信息；以及，第一信息可指示第二设备在频带组合2包括的频带B上的相位信息，相当于指示第二设备在CC4上的相位信息。
可选的，第二设备在第一资源组合中的第一资源上的相位信息，可以包括如下一项或多项：第二设备在第一资源组合中的第一资源上的相位，第二设备在第一资源组合中的第一资源上的相位个数，第二设备在第一资源组合中的第一资源上的相位取值集合或相位取值范围，第二设备在第一资源组合中的第一资源上的相位误差信息，或，第二设备在第二 资源上与第二设备在第一资源组合中的第一资源上的相位差。其中，第二资源是M个资源包括的除了第一资源外的另一个资源，例如第二资源包括在第二资源组合中。
第二设备在第一资源组合中的第一资源上的相位，可以是第二设备在第一资源组合中的第一资源对应的通道上发送信号时的实际相位，或者称为绝对相位，即，是第二设备在第一资源组合中的第一资源对应的通道上发送信号时的相位的实际值。或者，第二设备在第一资源组合中的第一资源上发送信号时的相位，可以是第二设备在第一资源组合中的第一资源对应的通道上发送信号时的相对相位，该相对相位例如为第二设备在第一资源组合中的第一资源对应的通道上发送信号时的实际相位与参考相位的差值。
参考相位例如为第一信息所指示的相位中的最大值或最小值，或为第一信息所指示的相位中的某一个相位。例如，第一信息指示了3个相位，分别为90°、180°、270°，则参考相位可以是90°或270°，或者参考相位也可以是这3个相位中的任意一个相位，例如180°。通过这种方式，只需要上报一个绝对值(例如最大值)作为参考相位，其它相位只需上报与该参考相位的相对值，数值较小，可节省比特数。或者，参考相位也可以不根据第一信息确定，而是采用某一固定值，例如180°，该固定值可由第一设备设置并通知第三设备，或者由第三设备设置并通知第一设备，或者由第一设备和第三设备协商确定，或者由LMF设置，或者通过协议预定义，或者预配置在第一设备和/或第三设备中。以第一资源组合中的第一资源对应一个通道为例，第二设备在第一资源组合中的第一资源对应的通道上发送信号时的实际相位为90°，则第二设备在第一资源组合中的第一资源上的相位信息可以包括90°。又例如，参考相位为90°，第二设备在第一资源组合中的第一资源对应的通道上发送信号时的实际相位为90°，则第二设备在第一资源组合中的第一资源上的相位信息可以包括0°。如果第一信息包括第二设备在第一资源组合中的第一资源上的相位，则第一设备可直接获知第二设备在第一资源组合中的第一资源上的相位，从而确定这些信号之间的相位差，无需再进行额外的操作，较为简单。
第二设备在第一资源组合中的第一资源上的相位个数，可以包括第二设备在第一资源组合中的第一资源上所对应的通道个数。例如，如果第二设备在第一资源组合中的第一资源对应的通道的数量为1，则第二设备在第一资源组合中的第一资源上的相位个数为1或者0；或者，如果第二设备在第一资源组合中的第一资源对应的通道的数量大于1，则第二设备在第一资源组合中的第一资源上的相位个数大于或等于1。可选的，第二设备在第一资源组合中的第一资源上的相位个数与第二设备在第一资源组合中的第一资源上对应的通道的个数相等。第一设备根据第二设备在第一资源组合中的第一资源上的相位个数，就能获得从第一资源组合中的第一资源上接收到的信号之间的相位差信息。例如，第二设备在第一资源组合中的第一资源上的相位个数为1或者0，表明第二设备在第一资源组合中的第一资源上发送信号时共用一个通道，那么第一设备能够确定，第一设备在第一资源组合中的第一资源上接收到的不同信号之间的相位差为0。又例如，第二设备在第一资源组合中的第一资源上的相位个数为4，表明第二设备在第一资源组合中的第一资源上发送信号时可能采用4个不同的通道，那么第一设备能够确定，第一设备在第一资源组合中的第一资源上接收到的两个信号之间的相位差的绝对值有4种可能，例如0°、90°、180°、270°，从而为第一设备确定测量信息提供辅助。
第二设备在第一资源组合中的第一资源上的相位取值集合或相位取值范围，可以包括第二设备在第一资源组合中的第一资源所对应的一个或多个通道上发送信号时的相位取 值集合或相位取值范围。其中，第二设备在第一资源组合中的第一资源上的相位取值集合，可以是指公式1中的的取值集合，或者是公式1中的的取值集合。同理，第二设备在第一资源组合中的第一资源上的相位取值范围，可以是指公式1中的的取值范围，或者是公式1中的的取值范围。例如第二设备在第一资源组合中的第一资源上发送信号时使用的一个通道的分频系数为4，则第一信息可包括该通道对应的相位取值集合或相位取值范围，如{(-5°，5°),(85°，95°),(175°，185°),(265°，275°)}，该相位取值集合或相位取值范围为公式1中的的取值集合。其中，(x，y)，表示取值范围为大于x且小于y，例如(85°，95°)，可表示取值范围为大于85°且小于95°。
又例如，第一信息可包括第二设备在第一资源组合中的第一资源上对应的一个通道的相位取值集合，例如为{0°，90°，180°，270°}，该相位取值集合例如为公式1中的的取值集合。第一设备获得了第二设备在第一资源组合中的第一资源上的相位取值集合或相位取值范围，就可以据此确定第二设备在第一资源组合中的第一资源上的相位信息。具体确定方式将在后文介绍。
第二设备在第一资源组合中的第一资源上的相位误差信息，可以包括第二设备在第一资源组合中的第一资源所对应的一个或多个通道上发送信号时的相位误差信息。第二设备在第一资源组合中的第一资源所对应的一个通道上发送信号时的相位误差信息，可包括第二设备在第一资源组合中的第一资源所对应的一个通道上发送信号时的相位值的误差信息，或者，包括第二设备在第一资源组合中的第一资源所对应的一个通道上发送信号时的相位取值集合的误差信息。而第二设备在第一资源组合中的第一资源所对应的一个通道上发送信号时的一个相位(实际相位)的误差信息，可包括如下一项或多项：相位误差上界，相位误差下界，相位误差的均值，相位误差的方差，相位误差的标准差，或，相位误差范围。例如第二设备在第一资源组合中的第一资源所对应的一个通道上发送信号时的一个相位的误差信息为{-10°,10°}，这表明该相位有正负10°的误差。对于第一设备来说，示例性地，可根据相位误差信息，通过搜索算法确定第二设备在第一资源组合中的第一资源上发送信号时的相位。相位误差信息可作为辅助信息，第一设备无需进行全范围搜索，提高了搜索效率。
第二设备在第二资源与第一资源组合中的第一资源上的相位差，可以包括第二设备在第二资源对应的通道上与第一资源组合中的第一资源对应的通道上发送信号时的相位差。例如此时的第二资源包括在第二资源组合中，第二资源组合与第一资源组合可以是同一个资源组合，或者是不同的资源组合。例如，M个资源包括资源1～资源3，M个资源属于2个资源组合，其中资源组合1包括资源1和资源2，资源组合2包括资源2和资源3。示例性地，第一信息可以包括以下一项或多项：第二设备在资源组合1中的资源1上与第二设备在资源组合1中的资源2上的相位差，第二设备在资源组合1中的资源1上与第二设备在资源组合2中的资源2上的相位差，第二设备在资源组合1中的资源1上与第二设备在资源组合2中的资源3上的相位差，第二设备在资源组合1中的资源2上与第二设备在资源组合2中的资源2上的相位差，第二设备在资源组合1中的资源2上与第二设备在资源组合2中的资源3上的相位差，以及第二设备在资源组合2上中的资源2与第二设备在资源组合2中的资源3上的相位差。这样，当第二设备在相应的资源上发送信号时，第一设备能获知相应信号之间的相位差。
可选的，第一信息可以包括不为0的相位差，如果第二设备在两个资源上发送信号时的相位差为0，则该相位差可以不包括在第一信息中。例如，如果第二设备在第二资源上 与第一资源组合中的第一资源上的相位差不为0，则第一信息可以包括该相位差；而如果第二设备在第二资源上与第一资源组合中的第一资源上的相位差为0，则第一信息可以不包括该相位差。例如采用如上的示例中第一信息包括所有列举项的情况，如果第二设备在资源组合2中的资源2上与第二设备在资源组合2中的资源3上发送信号时的相位差为0，则该相位差可以不包括在第一信息中。对于第一设备来说，如果发现第一信息并未包括某些资源之间的相位差，则可以确定这些资源之间的相位差为0。这样既能够使得第一设备获得不同资源之间的相位差，也能减小信令开销。
可选的，第一信息也可以包括为0的相位差。例如，如果第二设备在两个资源上发送信号时的相位差不为0，则该相位差可以不包括在第一信息中。对于第一设备来说，如果发现第一信息并未包括某些资源之间的相位差，则可以确定这些资源之间的相位差不为0。这样既能够使得第一设备获得不同资源之间是否存在相位差，也能减小信令开销。
因为一个相位差至少涉及两个资源，例如第二设备在第二资源组合中的第二资源上与第二设备在第一资源组合中的第一资源上的相位差就涉及第二资源组合中的第二资源以及第一资源组合中的第一资源，因此可选的，该相位差可以重复包括在第一信息中。例如第一信息可包括第一资源组合中的第一资源的信息，则第一资源组合中的第一资源的信息可以包括该相位差；第一信息还包括第二资源组合中的第二资源的信息，则第二资源组合中的第二资源的信息也可包括该相位差。或者，第一信息也可以只包括一次该相位差，换句话说，该相位差在第一信息中只出现一次。例如第一信息包括第一资源组合中的第一资源的信息，第一资源组合中的第一资源的信息可以包括该相位差；第一信息还包括第二资源组合中的第二资源的信息，第二资源组合中的第二资源的信息可以不包括该相位差，可选地，第一信息可包括与第二资源组合中的第二资源对应的第一指示，第一指示可以指示第一资源组合中的第一资源，以表示该相位差包括在第一资源组合中的第一资源的信息中。这种方式能够减小信令开销。
另外，第一信息还可包括第二设备在M个资源中的其他资源上的相位信息。对此可参考如上对于第一资源的介绍，不多赘述。
2、方式2。
在一些场景下，第二设备在一个或多个频带组合上会使用同一个通道，或者无论一个频带属于哪个频带组合，第二设备在该频带上都使用同一个通道，或者无论一个载波属于哪个频带组合，第二设备在该载波上都使用同一个通道，为此，提出方式2。
第一信息可包括第二设备在M个资源中的至少一个资源上的相位信息。例如M个资源中的一个资源为第一资源，第一信息可包括第二设备在第一资源上的相位信息。
可选的，第一资源为频带组合，M个资源为M个频带组合。或者，第一资源例如为频带，M个资源为M个频带。或者，第一资源为载波，M个资源为M个载波。方式2较为简单，能够节省第一信息所带来的传输开销。
可选的，第一信息可以包括不为0的相位差，如果第二设备在两个资源上发送信号时的相位差为0，则该相位差可以不包括在第一信息中。例如，如果第二设备在第二资源上与第二设备在第一资源上发送信号时的相位差不为0，则第一信息可以包括该相位差；而如果第二设备在第二资源上与第二设备在第一资源上发送信号时的相位差为0，则第一信息可以不包括该相位差。其中，第二资源为M个资源中除了第一资源外的一个资源。
可选的，第一信息也可以包括为0的相位差。例如，如果第二设备在两个资源上发送 信号时的相位差不为0，则该相位差可以不包括在第一信息中。
因为一个相位差至少涉及两个资源，例如第二设备在第二资源上与第二设备在第一资源上发送信号时的相位差就涉及第二资源以及第一资源，因此可选的，该相位差可以重复包括在第一信息中。关于该部分内容，可参考前述方式1的相关介绍。
应理解，第一资源为M个资源中的任意资源。
3、方式3。
例如M个资源中的一个资源为一个资源集合，则M个资源可以是M个资源集合。
可选的，资源集合为载波集合，一个资源集合可包括一个或多个载波。例如，第二设备在一个资源集合所包括的载波上发送信号时，所使用的通道相同；第二设备在不同的资源集合上发送信号时，所使用的通道不同。即，资源集合与通道是对应的关系。以图1为例，例如第二设备在其中的频带A包括的CC1和CC2上发送信号时，均使用通道1；第二设备在频带B包括的CC3上发送信号时，使用通道2；第二设备在频带B包括的CC4上发送信号时，使用通道3。那么，CC1和CC2可以属于一个载波集合，例如称为载波集合1；CC3属于另一个载波集合，例如称为载波集合2；CC4属于又一个载波集合，例如称为载波集合3。
可选的，在这种实现方式下，例如M个资源包括第一资源，第一资源是M个资源中的任一个资源，第一资源可以是一个资源集合，例如称为第一资源集合。对于第一资源集合来说，第一信息可包括以下一项或多项：第二设备在第一资源集合上的相位信息，第一资源集合的标识，或，第一资源集合中的资源标识。
继续以第一资源集合为例，可选的，第二设备在第一资源集合上的相位信息，可以包括如下一项或多项：第二设备在第一资源集合上的相位，第二设备在第一资源集合上的相位个数，第二设备在第一资源集合上的相位取值集合或相位取值范围，第二设备在第一资源集合上的相位误差信息，或，第二设备在第二资源集合与第一资源集合上的相位差。其中，第二资源集合是M个资源集合中除了第一资源集合外的另一资源集合。
第二设备在第一资源集合上的相位，可以是第二设备在第一资源集合对应的通道上发送信号时的实际相位，或者称为绝对相位，即，是第二设备在第一资源集合对应的通道上发送信号时的相位的实际值。或者，第二设备在第一资源集合上的相位，可以是第二设备在第一资源集合对应的通道上发送信号时的相对相位，该相对相位例如为第二设备在第一资源集合对应的通道上发送信号时的实际相位与参考相位的差值。对此的更多介绍可参考上述第一种实现方式。
第二设备在第一资源集合上的相位个数，可以包括第二设备在第一资源集合所对应的通道个数。对此的更多介绍可参考上述第一种实现方式。
第二设备在第一资源集合上的相位取值集合或相位取值范围，可以包括第二设备在第一资源集合所对应的通道上发送信号时的相位取值集合或相位取值范围。对此的更多介绍可参考上述第一种实现方式。
第二设备在第一资源集合上的相位误差信息，可以包括第二设备在第一资源集合所对应的通道上发送信号时的相位误差信息。第二设备在第一资源集合所对应的通道上发送信号时的相位误差信息，可包括第二设备在第一资源集合所对应的通道上发送信号时的相位值的误差信息，或者，包括第二设备在第一资源集合所对应的一个通道上发送信号时的相位取值集合的误差信息。而第二设备在第一资源集合所对应的通道上发送信号时的一个相 位(实际相位，或相位取值集合中的任一个相位)的误差信息，可包括如下一项或多项：相位误差上界，相位误差下界，相位误差的均值，相位误差的方差，相位误差的标准差，或，相位误差范围。
第二设备在第二资源集合与第一资源集合上的相位差，可以包括第二设备在第二资源集合对应的通道上与第一资源集合对应的通道上发送信号时的相位差。
可选的，第一信息可以包括不为0的相位差，如果第二设备在两个资源集合上发送信号时的相位差为0，则该相位差可以不包括在第一信息中。例如，如果第二设备在第二资源集合上与第二设备在第一资源集合上的相位差不为0，则第一信息可以包括该相位差；而如果第二设备在第二资源集合上与第二设备在第一资源集合上的相位差为0，则第一信息可以不包括该相位差。
可选的，第一信息也可以包括为0的相位差。例如，如果第二设备在两个资源集合上发送信号时的相位差不为0，则该相位差可以不包括在第一信息中。
因为相位差至少涉及两个资源，例如第二设备在第二资源集合上与第二设备在第一资源集合上发送信号时的相位差就涉及第二资源集合以及第一资源集合，可选的，该相位差可以重复包括在第一信息中，关于该部分内容可参考前述方式1的相关介绍。
另外，第一信息还可包括第二设备在M个资源集合中的其他资源集合上的相位信息。对此可参考如上对于第一资源集合介绍，不多赘述。
4、方式4。
在一些场景下，一个设备可能使用同一个通道，即，对于该设备来说，无论在哪个资源上发送信号，所使用的通道都是相同的。为此提出方式4。
第一信息可包括第二设备的相位信息，该相位信息适用于M个资源中的至少一个资源。例如在这种情况下，第一信息只需指示或包括第二设备发送信号时的相位信息即可，由此能够节省第一信息的信令开销，且简化指示方式。
另外，根据如上介绍可知，如果第二设备在一个通道内发送多个信号，则对第二设备来说，这多个信号之间的相位可以是连续的。因此，第一信息也可供网络配置资源时进行参考，例如，尽量将待发送的信号(例如第一信号)配置在同一个通道内，以减少接收端的复杂度。
可选的，第一信息可以包括在第二设备的能力信息中，关于该部分内容的介绍可参考后文将要介绍的图6所示的实施例。
S402、第二设备在M个资源中的一个或多个资源上发送第一信号。相应的，第一设备在M个资源中的一个或多个资源上接收来自第二设备的第一信号。其中，第一信号可以通过广播、组播或单播等方式发送，如果第一信号为广播或组播，则可能有多个设备能够接收第一信号，第一设备例如为其中一个接收设备。如果第一信号为单播，则第一信号为第二设备发送给第一设备的信号。
可选的，第二设备可以在一个或多个资源上同时发送第一信号。或者，这一个或多个资源上的第一信号也可以不是同时发送的，例如第二设备采用跳频方式发送。
其中，第一信号可包括S个信号，S可以是大于或等于2的整数。例如，可将第二设备在一个频带上发送的信号理解为一个信号，M个资源例如为M个频带，则第一信号可以在M个频带中的S个频带上发送。又例如，可将第二设备在一个载波上发送的信号理解为一个信号，M个资源例如为M个载波，则第一信号可以在M个载波中的S个载波上发 送，示例性地，这S个载波可以是参与载波聚合的S个分量载波。又例如，将第二设备在一个BWP上发送的信号理解为一个信号，M个资源例如为M个BWP，则第一信号可以在M个BWP中的S个BWP上发送，这S个BWP可以包括在一个或多个载波内。或者，第一信号的划分粒度可以更小，例如将第二设备在一个频率单元上发送的信号理解为一个信号，M个资源例如为M个频率单元，则第一信号可以在M个频率单元中的S个频率单元上发送，这S个频率单元可以包括在一个或多个载波内。其中，频率单元的粒度小于BWP的粒度，例如频率单元所占用的频域范围小于BWP占用的频域范围。
可参考图5，其中的f1～f5表示5个频率单元。例如，第二设备在图5中的频带A上发送信号时，使用通道1；第二设备在图5中的频带B内的CC3上发送信号时，使用通道2；第二设备在图5中的频带B内的CC4上发送信号时，使用通道3。第一信号例如包括信号1和信号2，例如信号1和信号2可以在不同的频带上发送，例如分别在f1和f3上发送；或者，信号1和信号2可以在同一个频带内的非连续载波上发送，例如分别在f3和f4上发送；或者，信号1和信号2可以在同一个频带内的连续载波上发送，例如分别在f1和f2上发送；或者，信号1和信号2可以在同一个载波上发送，例如分别在f4和f5上发送。
可选的，第一信号所包括的全部或部分信号可用于定位。例如第一信号包括定位参考信号。
S403、第一设备获得测量信息。其中，该测量信息可以基于第一信号以及第一信息确定。或者S403也可以替换为，第一设备根据第一信号和第一信息确定测量信息。
示例性地，第一设备根据第一信息，可以确定第一信号所包括的信号的相位信息，和/或，确定第一信号所包括的各个信号之间的相位差。一种可能的实现方式中，第一设备可根据确定的相位差对第一信号包括的部分或全部信号进行相位补偿，获得一个大带宽信号的测量结果，例如将该大带宽信号称为第二信号，第二信号的带宽接近(可略小于或等于或略大于)第一信号所包括的各个信号的带宽之和。
例如，第一设备根据第二信号可以估计第二设备到第一设备的传输时延，该测量信息可以包括该传输时延的信息。可选的，该传输时延可用于UE进行定位。
又例如，第一设备可根据第二信号进行信道估计，所述信道指的是第二设备发送的第一信号(或者说UE接收到的第一信号)所经过的信道。一种可能的实现方式中，第一设备根据第一信号的相位信息，获得较为精确的信道估计结果。第一设备所获得的信道估计结果可包括如下一项或多项：信道参数，信道矩阵，信道衰落矩阵，信道冲激响应矩阵，多径的时延，簇的能量，或，信道参数估计结果的分布。可选地，该信道估计结果可用于通信或定位。
其中，可由第一设备对UE进行定位。例如第一设备是UE，第二设备是接入网设备。一种可能的实现方式中，参与对该UE定位的接入网设备可能有一个或多个，对于参与定位的接入网设备的信号，UE均执行图4所示的实施例，从而可以获得对应于每个接入网设备的测量信息。在获得多个测量信息后，UE可根据获得的多个测量信息对该UE进行定位。或者，也可由其他设备(例如LMF或接入网设备或其它UE等)对UE进行定位，例如第一设备可将获得的多个测量信息发送给其他设备(例如LMF或接入网设备或其他UE等)，由所述其他设备对该UE进行定位。
或者，例如第一设备是接入网设备，第二设备是UE。一种可能的实现方式中，参与对该UE定位的接入网设备可能有一个或多个，这一个或多个接入网设备均可通过图4所 示的实施例获得测量信息。例如其中的一个接入网设备可以从多个接入网设备中的其他接入网设备接收测量信息，从而其中的一个接入网设备可以获得多个测量信息，那么该接入网设备可以根据获得的多个测量信息对UE进行定位，该接入网设备例如为UE的服务接入网设备，或者是参与定位的任一个接入网设备；或者，各个参与定位的接入网设备可将获得的测量信息发送给LMF或其他UE，由其对UE进行定位。
可选的，用于对UE进行定位的设备(接入网设备、UE、LMF或校准设备等)可采用的定位技术为到达时间(time of arrival，TOA)定位、到达时间差(time difference of arrival，TDOA)定位、上行到达角(uplink angle-of-arriva，UL-AoA)定位、下行离开角(downlink angle of departure，DL-AoD)定位，多次往返时间(multiple round trip time,multi-RTT)定位，载波相位定位(carrier phase positioning)，或者这些定位方法中某些方法的融合定位等，不做限制。
本申请实施例中，第一信息可包括第二设备在M个资源对应的相位信息。那么第一设备在M个资源中的一个或多个资源上接收信号后，可以根据第一信息确定所接收的信号的相位信息，第一设备可以进一步采用相应的方式减小或消除该相位差，以提高所获得的测量信息的准确性。例如该测量信息的一种应用场景为，该测量信息可用于对第二信息进行定位，从而提高对于第二设备的定位精度。
为了解决相同的技术问题，本申请实施例提供第二种通信方法。请参考图6，为该方法的流程图。
S601、第二设备发送第一信息。相应的，第一设备接收第一信息。本申请实施例中，第三设备与第二设备例如为同一设备。
第一信息可包括第二设备在M个资源上的能力信息，或者说，第一信息包括第二设备与M个资源关联的能力信息，M为正整数。其中，根据第二设备在一个资源上的能力信息，能够确定第二设备在该资源上的相位信息。第二设备在一个资源上的相位信息，可以理解为是第二设备在该资源上发送信号时的随机相位信息，或者理解为，是第二设备在该资源对应的通道上发送信号时的随机相位信息。对此的更多内容可参考图4所示的实施例的S401。
本申请实施例中，第一信息也可以有多种实现方式，下面举例介绍。
1、方式A。
M个资源可以属于一个或多个资源组合，第一信息可以包括第二设备在这一个或多个资源组合中的至少一个资源组合中的资源上的能力信息。以M个资源中的第一资源为例，第一资源可以为M个资源中的任一个资源，M个资源包括第一资源。第一资源属于第一资源组合。在这种实现方式下，第一信息可以包括第二设备在第一资源组合中的第一资源上的能力信息。
可选的，当资源组合为频带组合，此时，第一资源组合为第一频带组合。由于一个频带组合可以包括一个或者多个载波，或者包括一个或者多个频带，因此，第一资源可以是一个载波或者一个频带。如果第一资源为一个频带，那么第一信息可包括第二设备在一个或多个频带组合中的至少一个频带组合中的部分或全部频带上的相位信息，可理解为，第一信息是按照每频带组合每频带(perBCperBand)的粒度上报；或者，第一资源为一个载波，那么第一信息可包括第二设备在一个或多个频带组合中的至少一个频带组合中的部分或全部载波上的相位信息，可理解为，第一信息是按照每频带组合每载波(perBCperCC) 的粒度上报。
上述方式A中，第一资源可属于多个资源组合，或者说，M个资源所包括的多个资源组合中，有两个或者两个以上的资源组合均包括第一资源，此时，第一资源可以对应多个通道。在前文介绍了，第一资源可以属于第一资源组合，在一种可选的方式中，如果第一资源对应多个通道，则第一资源属于多个资源组合。以第一资源属于第一资源组合和第二资源组合为例，此时，第一信息可以包括第二设备在第一资源组合中的第一资源上的相位信息，和第二设备在第二资源组合中的第一资源上的相位信息。对此更多的介绍等内容可参考图4所示的实施例中的S401。
示例性地，第二设备如果在同一频带上的两个非连续的载波上发送信号，可以通过两个通道发送，不同的载波可对应不同的通道，即，非连续载波可能会使用不同的通道。例如，图1中的CC3和CC4是属于频带B的非连续载波，频带B属于两个频带组合，例如分别为频带组合1和频带组合2，则可能存在两种情况，对此可参考图4所示的实施例中的S401。
如果是第一种情况，第二设备在同一个频带所包括的非连续的载波上的能力信息可能是不同的。为了将第二设备在该频带上的能力信息均告知第一设备，可将该频带分别包括在不同的频带组合中，且该频带在不同的频带组合中包括的可以是不同的载波，这样就可将第二设备在非连续载波上的能力信息指示给第一设备。例如，图1中的CC3和CC4是属于频带B的非连续载波，频带B属于两个频带组合，例如分别为频带组合1和频带组合2。例如，频带B为图2中的频带n41，频带组合1为图2中的BC1，频带组合2为图2中的BC2。一种可能的实现方式，在频带组合1中频带B包括CC3，例如为图2中BC1下的频带n41所包括的8个分量载波中的其中一个分量载波；在频带组合2中频带B包括CC4，例如为图2中BC2下的频带n41所包括的4个分量载波中的其中一个分量载波。第一信息可指示第二设备在频带组合1包括的频带B上的能力信息，相当于指示第二设备在CC3上的相位信息；以及，第一信息可指示第二设备在频带组合2包括的频带B上的能力信息，相当于指示第二设备在CC4上的能力信息。
可选的，第二设备在第一资源组合中的第一资源上的能力信息，可以包括如下一项或多项：第一资源组合中的第一资源对应的资源粒子的数量，第二设备在第一资源组合中的第一资源对应的分频系数，或，第一资源组合中的第一资源的频率范围。
第一资源组合中的第一资源对应的资源粒子的数量，可以理解为是第二设备在第一资源组合中的第一资源上发送信号时所使用的通道的数量。例如，第一资源组合中的第一资源对应一个或多个资源粒子，资源粒子与通道是一一对应的关系，也就是说，第二设备在第一资源组合中的第一资源上对应一个或多个通道。资源粒子例如为载波，或者为载波组合(例如第一资源内对应于同一个通道的载波可以属于一个载波组合)，或者为BWP，或者为BWP组合，或者为粒度小于BWP的频率单元或频率单元组合。那么，如果第一资源组合中的第一资源对应的资源粒子的数量为P，则第二设备在第一资源组合中的第一资源上发送信号时使用的通道的数量为P，P为正整数。第一设备根据资源粒子的数量就能确定第二设备在第一资源组合中的第一资源上发送信号时所使用的通道的数量，而根据该通道的数量，第一设备能够确定第二设备在第一资源组合中的第一资源上发送信号时的相位。例如，第二设备在第一资源组合中的第一资源上发送信号时所使用的通道的数量为1，那么第一设备能够确定，第一设备在第一资源组合中的第一资源上接收到的不同信号之间的 相位差为0。又例如，第二设备在第一资源组合中的第一资源上发送信号时所使用的通道的数量为4，那么第一设备能够确定，第一设备在第一资源组合中的第一资源上接收到的两个信号之间的相位差的绝对值有4种可能，例如0°、90°、180°、270°，从而为第一设备确定测量信息提供辅助。
第二设备在第一资源组合中的第一资源对应的分频系数，例如包括第二设备在第一资源组合中的第一资源上发送信号时使用的各个通道所关联的分频系数，这体现了第二设备在第一资源组合中的第一资源对应的通道上的分频能力。例如第二设备在第一资源组合中的第一资源上发送信号时使用一个通道，则第二设备在第一资源组合中的第一资源对应的分频系数可包括该通道的分频系数，例如该通道的分频系数为4或8等。第一设备如果获知了一个通道的分频系数，就能确定第二设备在该通道上发送的信号的相位取值集合(例如一个通道的分频系数为4，则该通道对应的相位取值集合为{0°,90°,180°,270°})，从而能够确定第二设备在该通道上发送的信号的相位。
第一资源组合中的第一资源的频率范围(或者说，第一资源组合中的第一资源对应的频率范围)，例如包括第二设备在第一资源组合中的第一资源上发送信号时使用的各个通道的频率范围。例如，第二设备在第一资源组合中的第一资源上发送信号时使用的一个通道的频率范围为2.5GHz～3.5GHz，则第一设备能够确定，第二设备在该频率范围内所发送的信号之间的相位差为0。又例如，第二设备在第一资源组合中的第一资源上发送信号时使用的一个通道的频率范围1为A，第二设备在第一资源组合中的第一资源上发送信号时使用的另一个通道的频率范围2为B。可选的，第二设备与第一资源组合中的第一资源关联的频率范围还可以指示频率范围1与频率范围2的相位差，例如为C，则第二设备在这两个频率范围内所发送的信号之间的相位差为C。如此，第一信息可供网络配置资源时进行参考，例如，尽量将待发送的信号(例如第一信号)配置在同一个通道关联的频率范围内，以减小接收端的复杂度。
2、方式B。
在一些场景下，第二设备在一个或多个频带组合上会使用同一个通道，或者无论一个频带属于哪个频带组合，第二设备在该频带上都使用同一个通道，或者无论一个载波属于哪个频带组合，第二设备在该载波上都使用同一个通道，为此，提出方式B。

可选的，第一信息可以包括在第二设备的能力信息中，该能力信息的消息载体例如为LPP提供能力(LPP ProvideCapabilities)消息或UE能力信息(UECapabilityInformation)消息。该能力信息可称为能力信息A，例如为第二设备的总的能力信息。例如第二设备为UE，第一设备为LMF，能力信息A承载在LPP提供能力消息中，那么UE可将第一信息添加到LPP提供能力消息中发送给LMF。例如第二设备为UE，第一设备为接入网设备，那么UE可将第一信息添加到UE能力信息消息中发送给接入网设备，而无需再额外向接入网设备发送第一信息，从而节省信令开销。本申请实施例中，由于第一信息可以包括在第二设备的能力信息A中，因此认为第一信息包括的是第二设备在M个资源上的能力信息。下面以方式A、以及以UE能力信息消息为例，介绍第一信息包括在第二设备的UE能力信息消息中的一种方式。
以第二设备的UE能力信息消息通过图2所示的方式上报为例。例如参与载波聚合的载波为频带n41上的CC1和频带n78上的CC2，则第一信息可以包括第二设备在BC2中的频带n41上的能力信息，以及包括第二设备在BC2中的频带n78上的能力信息。例如图2中，在n41频带对应的特征集2包括的特征集上行ID2对应的能力信息中，可以包括第二设备在BC2中的频带n41上的能力信息，或者说，指示第二设备在频带n41的CC1上的相位信息；在n78频带对应的特征集2包括的特征集上行ID2对应的能力信息中，可以包括第二设备在BC2中的频带n78上的能力信息，或者说，包括第二设备在频带n78的CC2上的能力信息。

关于S603的更多内容，可参考图4所示的实施例中的S403。
本申请实施例中，第一信息可包括第二设备在M个资源的能力信息。那么第一设备在M个资源中的一个或多个资源上接收信号后，可以根据第一信息确定所接收的信号的相位信息，从而在获得测量信息时考虑所接收的信号的相位信息，例如可以采用相应的方式减小或消除不同信号之间的相位差，以提高所获得的测量信息的准确性。例如该测量信息的一种应用场景为，该测量信息可用于对第二设备进行定位。那么，通过估计所接收的信号的相位信息，能够减小该相位信息对于定位精度的影响，从而提高对于第二设备的定位精度。
